Support and buffer structure for shoe body

ABSTRACT

Disclosed is a support and buffer structure for shoe body, wherein an arcuate hollow rubber portion is attached on the top surface of a sole plate. A balance seat in form of a curved larger area is attached in turn on the top surface of the rubber portion so that an applied body weight can be uniformly distributed over the balance seat and supported and buffered by the rubber portion to achieve the purpose of shock absorption, comfortableness and stability when wearing it.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to a support and buffer structure of shoe body, and specifically, it relates to a hollow structure capable of supporting, buffering, and shock absorbing.

2. The Prior Arts

It is noticed that some diseases regarding bones or joints, such as backache of joint retardation, are incurred by improper sports impacts. To take a run by bare feet for instance, some harmful oscillation waves are produced from bottom to top of a human body to impose an overlarge load to people's bones or joints, which is considered today very bad to a human skeleton.

For improvement, a support and buffer structure for shoe body of the present invention is undoubtedly one of the preferred options for preventing sports harm.

SUMMARY OF THE INVENTION

The primary object of the present invention is to provide a support and buffer structure for shoe body, in which a shock-absorption composition is formed at a rear segment of shoe body for supporting and buffering a gravity applied by means of an arcuate rubber portion.

In order to realize above-mentioned object, an arcuate hollow rubber portion is attached on the top surface of a sole plate. A balance seat in form of a curved larger area is attached in turn on the top surface of the rubber portion so that an applied body weight can be uniformly distributed over the balance seat and supported and buffered by the rubber portion to achieve the purpose of shock absorption, and also comfortableness as well as stability.

For more detailed information regarding advantages or features of the present invention, at least one example of preferred embodiment will be described below with reference to the annexed drawings.

BRIEF DESCRIPTION OF THE DRAWINGS

The related drawings in connection with the detailed description of the present invention to be made later are described briefly as follows, in which:

FIG. 1 is a side view of the present invention;

FIG. 2 is an exploded structural side view of the present invention;

FIG. 3 is a sectional view taken along line A-A of FIG. 1; and

FIG. 4 is a side view of the present invention applied to a shoe body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 and 2, a support and buffer structure in accordance with the present invention comprises a sole plate 1, a rubber portion 2, and a balance seat 3, and is arranged in the heel portion for making use of its shock-absorption ability.

The sole plate 1, which is the lowest layer of shoe, is configured to try matching with human sole. In doing so, the present invention is provided to the rear segment of the sole plate 1 with the rubber portion 2. The rubber portion 2 is an arcuate hollow structure having a space 21 in the middle portion thereof for communicating with the outside world, in which a relatively thinner portion above the central portion of the rubber portion 2 is extended forward and backward and from top to bottom to form a gradually thickened front and rear support portion 22, 23. In addition, the bottom of the rubber portion 2 is attached exactly on the surface of the sole plate 1 to thereby achieve the purpose of buffering, shock absorbing, and support strength enhancing. The balance seat 3 is a curved structure with large area having a local front end attached to the top surface of sole plate 1, and the rest large portion thereof is attached intimately to the top surface of the rubber portion 2 such that the rubber portion 2 is covered below. Besides, both sides of the balance seat 3 are arcuate protruding sides (as illustrated in FIG. 3) meant to match with the edge and arch of a human sole such that a person's weight can be uniformly distributed and transmitted to the rubber portion 2 below. Also, a stable balance seat 3 is considered instrumental to promote stability of movements.

In addition to shock-absorption function, the rubber portion 2, which may be constructed with a thermoplastic or thermo-foaming material, has to be strong enough to bear a person's weight, in which the thermoplastic material may include, but not limited to, thermoplastic polyurethane (TPU), thermoplastic rubber (TPR), and Nylon and the thermo-foaming material may include, but not limited to, polyurethane (PU), and ethylene-vinyl acetate copolymers (EVA).

FIG. 4 is a side view of the present invention applied to a shoe body. A vamp 4 is defined above the support and buffer structure of the present invention. The present invention is constructed by defining an arcuate hollow rubber portion 2 at a rear segment of sole in the shoe body to function for support and buffer; and a balance seat 3 on the rubber portion for distributing the momentum of human weight, which is rebounded by the rubber portion 2, in which the relatively thinner portion of the rubber portion 2 is designed to serve for a preliminary buffer stage while a front and a rear support portion 22, 23 thereof are designed to serve for a later buffer stage, so that the comfortableness and stability of a shoe sole can be effectively maintained.

In the above described, at least one preferred embodiment has been described in detail with reference to the drawings annexed, and it is apparent that numerous changes or modifications may be made without departing from the true spirit and scope thereof, as set forth in the claims below. 

1. A support and buffer structure for shoe body, comprising: a sole plate, which is provided with a rubber portion at a rear segment thereof; a rubber portion, which is formed of an arcuate hollow supporter in a middle portion thereof, and a bottom portion thereof is attached on the top surface of the sole plate; and a balance seat, which is formed of a curved larger area attached on the top surface of the rubber portion.
 2. The support and buffer structure as claimed in claim 1, wherein the rubber portion is formed in an arc curve having a space in a middle area thereof for communicating with the outside world, in which the wall above the middle area which is relatively thinner is extended forward and backward and from top to bottom to form respective gradually thickened front and rear support portions for being attached on the top surface of the sole plate.
 3. The support and buffer structure as claimed in claim 1, wherein the rubber portion is made of a thermoplastic material.
 4. The support and buffer structure as claimed in claim 1, wherein the rubber portion is made of a thermo-foaming material.
 5. The support and buffer structure as claimed in claim 1, wherein both sides of the balance seat are arcuate protruding sides meant to match with the edge and arch of a human sole.
